This got me thinking. I use a lot of colour in my paintings but my palette has evolved to always having cadmium yellow medium, ultramarine blue, winsor blue, dioxazine violet and alazarin crimson and often viridian squeezed onto the palette. These basic colours provide me with combinations that suit the Provence landscape. I add yellow ochre pale for some buildings, rocks and pathways and also use other colours as required. I use winsor and Newton oil paints as the consistency is right for me for both palette knife and brush.
I can't say that I have two favourites but there are certain combinations I love and here are two:
Pale purple and green/turquoise
This painting is based on the shimmering combination of the violet and turquoise
For the pale purple I mix diox purple with white, sometimes adding a touch of pink (permanent rose or al. crimson with white) or a touch of pale winsor blue depending upon the temperature I am trying to achieve. For the green turquoise I will mix a combination of phthalo blue, lemon yellow, white and often viridian and winsor blue to get the correct colour.
Yellow and purple
This combination is difficult to pull off because they are both such vibrant colours. It is important to make one of them more dominant than the other. In this painting the purple dominates but the yellow is the star
Of course the yellow doesn't need to be vibrant, the combination works just as well with purple and yellow ochre
